Abstract
The present invention relates to a preparation method of new-type green environment-protecting phosphorization solution for making metal surface treatment of steel and iron, etc. Said invented normal temp. phosphorization solution is made of phosphoric acid, zinc oxide, nitric acid, citric acid and fluoroboric acid through a certain reaction preparation process. It can be used under the condition of room temp. and is a multifunctional high effective phosphorization agent integrating removing oil, removing rust, phosphorization and desactivation into one body.
Description
The present invention relates to a kind of preparation method who is used for the new green environment protection phosphatization liquid of metal finishing such as iron and steel, belong to chemical industry and environmental technology field.
Along with the especially manufacturing continuous development of economy, the demand of metal conditioner is increasing.Phosphatization liquid is that iron and steel is carried out parkerized material.Phosphorization agent product in the market has long, shortcomings such as speed is slow, severe operational environment of treatment time mostly, in use can produce toxic gas or sediment, influences environmental quality.
The objective of the invention is to develop a kind of new environmental type, integrate deoil, the multifunctional efficient phosphorization agent prescription of rust cleaning, phosphatization, passivation, the phosphatization liquid of being developed can be used at normal temperatures, reach energy-conservation, convenient, cost is low, the effect of environmental protection.
The prescription of phosphorization agent involved in the present invention is as follows:
Content of drug, the mg/L effect
Phosphoric acid 600-650 provide PO
4 3+With free acidity, be reacted into main salt with ZnO
Nitric acid 130-150 accelerates phosphating reaction speed, reduces phosphatization temperature
Zinc oxide 230-250 provide Zn
2+
Nickelous nitrate 3-4 heavy metal accelerator, phosphatize phosphate coat fining agent
Zinc sulfate 6-7 provide Zn
2+, prevent film alligatoring crystallization
Sodium tetrafluoroborate 9 provides F
-Fining agent, the soda acid buffering
The slag agent falls in iron nitrate 1.6
Citric acid 8.5 complexing actions
Slag falls in EDTA 7-8
Copper sulfate 1.5 improves speed of response
Below in conjunction with the technological process of specific embodiment explanation based on aerobic microbiological fermentative preparation mud agricultural fertilizer.
Embodiment
Add 500 kilograms of 85% strong phosphoric acid in 3 tons of reactors, and 200 kilograms in 98% nitric acid, add 1000 kg of water, add other chemical agent according to this by said sequence then, hybrid reaction is even, proportion is about 1.6 normal temperature phosphating liquid product.
This product has the spies such as serviceability temperature is low, sediment is few, be easy to management, operating environment has no irritating odor Point, and life cycle is long, energy efficient.
